IMPROVEMENT IN ICE-CREEPERS.

Specification forming part of Letters Patent No. 135,629, dated February 1l, 1873.

To all whom it may concern:

Beit known that I, EBENEZER B. GoLBY, of Franklin, of the county of Merrimack and State of New Hampshire, have invented a new and useful Creeper or apparatus to be applied to a shoe or boot to prevent the wearer from falling or slipping on ice or in ascending or descending a hill or declivity; and Ido hereby declare the same to be fully described in the following specifica-tion and represented in the accompanying drawing, of which- Figure 1 is a top view, Fig. 2 a front elevation, Fig. 3 an end view, Fig. 4 a transverse section, and Fig. 5 a longitudinal section, of it.

It is to be applied to the heelfof a shoe or boot, to be arranged therewith in manner as shown in some of the above-mentioned iigures, wherein the heel is exhibited at H by dotted lines, it being fastened in place by screws going through holes in the sustaininglips and screwed into the heel.

In the drawing, A denotes a case or box iixed to the upper of two sustaininglips, B C, fastened together and arranged at a right angle to one another, the lower of such lips being, in form, an arc of a circular annulus.

lThe box A is open at bottom, and contains a movable serrated or sawtoothed spur, I), formed as shown in the drawing and particularly in side view in Fig. 6, it being chambered, as represented at a, to receive a cam, b, iixed on the end of an arbor, c, the said arbor being arranged in and so as to project from the box in manner as exhibited. The part of the arbor which projects from the box should be prismatio to enter a key such as shown in Fig. 7. On revolving the arbor by means of the said key the spur may be either drawn into the box or caused to project fromit, the cam holding the spur in either position.

From the above it will be seen that when the spur extends out of the box and below the heel it (the spur) will serve to prevent a person from slipping while walking or standing on ice or frozen ground, or going up or down a declivity; but when the spur is wholly within the box such spur will be protected from wear or injury.

I claim- In an ice-Creeper, the combination of either or both the lips B C with the box or caseA and the serrated spur D, provided with mechanism for opera-ting it, as described.
